I had a oil hydro once that the return pump pumped water from a wet pit into the tank, maybe 15 gallons, it had Imo pump and brass eeco valves. The consultant caught it on a full maintenance job and wanted all the oil changed. If you do it right that the tank, jack, lines ect and cost of over $300 a barrel haz mat cost to dispose of oil, plus labor plus cost of new oil. I got a air pump and put the air hoses into the tank left cover off of tank and after about a month the water evaperated out of the tank from the bubbles. I was watching the samples and it took almost 3 months for the water to separate from the oil on its own in a jar so the idea of waiting for it to sepatate in the power unit is not fast enough and you have to leave the elevator down. HAVE ANY OF YOU USED THIS METHOD OF REMOVING WATER FROM OIL WITH THE AIR BUBBLER METHOD.

Take the lid off the tank and run the hell out of it... get the oil hot and the water will evaporate even faster...

We have a filter pump that says it separates water from oil. That would take less time.

Still would have the water in the jack. Water is heavier than oil. You could argue that w/o oxygen no corrosion would take place but I wouln't want to be the one to explain it to a client/lawyer/consultant.

Good luck.

I once tried the filter method that promised to separate water from oil but the filter was about $100 and it needed replacement after 5 minutes. The water at the bottom of the jack will be mixed with the hydro oil, similar to a water hydro with soluble oil but in this case there is only a fraction of water in the system, there is not pockets of pure water, its all mixed.

Like I said, your best bet is to run the snot out of it, block the doors out so you have no doors, run top to bottom to get the oil really hot, and let the water evaoporate... it may take a few days depending on how much water you have in the system, but ALL the water will be gone...

We have a 4 stop, double motor and valve assy. That during construction someone left the lid off the tank and allowed our usual florida summer rains to fill the tank and the crew who put it in thought it was very thoughtful of the manufacturer to pre fill with oil....NOT, needless to say they added all the 55 drums and the next day we had MAYO in the tank. Anyways we tried the filter thing and it went through filters like strained peaches through a baby. We found an additive that we usually use was very helpful, added about 5gal. and left the lid off and in a week we were free and clear. The additive is made by Mullen Circle Brand inc. out of Chicago, they also make rope lube but ask for the Hydro oil additive it works.

Hi Clark I called that company today in Chicago and they dont sell a product to separate water from oil, all they have that is close is a type of radiator flush product for hydros that you dump in and run the car for a while and then change all the oil, Does that sound like the stuff you used, once you add this product you have to discard the oil. Jim

-- Jim (elevator555@hotmail.com), March 02, 2004.

No the stuff we use was an additive that stayed in the oil and we were able to keep it in use. I don't have any in my van so I don't have the name of it, but I'll check for the name at our shop. I think they market the additive as Anti Chatter? you may wanna check with them again, I don't think it was desighned to remove water it was desighned for light weight cars with inverted jacks who's valves and joints need extra lubrication. Like a Slick 50 for Hydro's. It worked on the water though, honestly. A Guy I know also buys a similar product from Catipiller and Ringhaver tractor shops, he said it work well too, just a bit more expensive. I'll see if the bottles have any model or name of product on in the A.M.

-- Clark (pdell200@comcast.net), March 03, 2004.

Hey Clark, the salesman did mention a anti chater lubricant and he said it his bigges seller, they are going to send a catalog, did that work to take out the water or just make a running elevator out of what you had.???? thanks Jim

-- Jim (elevator555@hotmail.com), March 03, 2004.

Clark is telling you the truth about the addative i know the job he is right has been running for two and a half years just fine with same water poluted oil all is good no more water.

-- Terry (socea@juno.com), March 03, 2004.

Jim, Thats the stuff, anti chatter it worked all clear of H20 for at least two years now, hope it works for ya, remember to use atleast 5 or 6 gallons and leave the lid of the tank for a few months. Let me know how it works out.
